Whoops =E2=80=A6.. sorry. I missed the word "Transmitter" Thought you were =
just looking for an OC reed Switch.

Some of the older Transmitters of some of the manufacturers had the ability=
 to use OC external contacts. I think that Napco's older transmitters are s=
till available. Have to use a resistor in the circuit IIRC.



You also might want to try Inovonics.
